Jan: Fixity - property of being unchanged Checksum - it's like digital fingerprint ( #Fixity ✅ and #Checksum ✅ - #DigiPresBingo)

AFAIK, there's only one existing Vim plugin for buffer checksums, and it's quite old, relying heavily on terminal tools. I've developed a newer version using Vim9Script and the V language. Contributions and ideas are welcome. #Vim #VLang #Checksum #Programming #vim9script

Quick question for my fellow Mac users: Is it true that there's no built-in CLI command to check a SHA256 checksum, and you need to install the entire GNU coreutils for that? 🤔 #MacOS #CLI #Checksum

@samirx Granted AFAIK @tails_live / @tails / #Tails does some #signature and #Checksum checks to enshure it's integrity, as anything but the seperate #PersistentStorage partition is mounted #ReadOnly...

Script validation with calc-sum and check-sum

https://tilvids.com/videos/watch/2314e855-11d6-4a2e-b995-c911fba04a62

Made good progress on my file integrity tools lately.

Calc-sum updates sha3-512 checksums in a hash-list.

When executing my scripts I can check the file integrity with check-sum while running. This is a security measure; sometimes I type in a file by accident without noticing. But now check-sum holds the script if the file has changed and the integrity check fails. For remote files this can of course also work as an extra security tool.

After some #Thunderbird update, I've started to get notices about incorrect S/MIME signatures in emails which was previously marked as correct. The error message was obscure - something about an unknown issue.

No quick solution was found. After some time, I've tried again to figure out what is the problem, and this Czech article solved it: https://www.postsignum.cz/files/navody/thunderbird_smime/index.html

Shortly - Thunderbird dropped support of #SHA1 #checksum in #SMIME signatures and failed to provide any human-readable error message in that regard.

I believe it is a suboptimal behavior for a number of reasons:

1. I can't avoid getting emails from this source and can't make them upgrade their certificate, really. I have only a choice either to drop the signature check completely or rely on the substandard check. Obviously, in this situation I prefer rather to see the results of the check and probably some info that it is, actually, substandard.

2. Solving the problem needs to realize it first. An obscure error message is not too helpful.

3. Such incidents actually undermine the opinion about #cryptographic #signature check. If you see some error, your first though is not "it is probably a #MITM attack" but "probably something is broken in the signature check".

The possibility to fix everything is, however, good.

Why is it so damn hard to do a checksum thing on linux mint? FFS. Is it just me? I tried following the instructions and it's like a bunch of steps and I can't even find the right place to get GnuPg.
I feel like I must be missing something.

#random: I'm obviously 69-times checking my files on the archive if ever it has been modified by sheer accident (by checksums and signing) so I couldn't be messed with extracting them again.

For the freaks out there, I also implemented a signature system just to be extra sure about the origin of the files. I also redid my pubkeys again (as I forgot my old one and couldn't revoke it).

You can check my PGP pubkey fingerprint on my bio.

Doing some checksum work to ensure the integrity of the files in the Windows Phone Emulator Images Archives (something I didn't do in the previous one with Windows Mobile).

Checksums for VHDs and BINs are available, in MD5, SHA-1, SHA-256 and CRC32 to verify the integrity of these large files (ranging from 77MB to 2.9GB).

#checksum #hash #Microsoft #windows #windowsphone #archive #tech #technology #mobile #phone #smartphone

I updated the sendmeshfile.sh script to include md5 checksums for the previous base64 line sent. This should allow "error detection" if a receiver misses a line (much notes in the bash comments):

My little utility to calculate the #checksum and #sha values seems finished. Done using #HollywoodMAL and #RapaGUI plugin so should be compatible even with #Amiga -like systems with #MUI, but need to try 😀
The source & compiled versions will be available somewhere, maybe on my Patreon page (for free), in the next days.

I've found difficulties on how I had to structure the code in order to refresh the GUI during long loops, I may write something about it and how it should be done properly.
